GENERA. 
I. BROWNLOWIEÆ. 
1. Brownlowia Roxs.—Flowers regular hermaphrodite ; calyx sub- 
campanulate, regularly or irregularly 3—5-dentate or 3—5-fid, valvate. 
Petals 5, narrow at base, unequal at apex ; preefloration contorted or 
imbricated. Stamens w, produced with the summit of the receptacle 
beyond the perianth in a small cylindrical column inserted below the 
germen, 5 of which are antherless, oppositipetalous elongated-peta- 
loid ; others disposed in 5 phalanges, alternate ; filaments thin, free or 
connate at base ; anthers 2-locular extrorse ; cells subglobose, rimose, 
finally confluent at apex. Carpels 3-5, alternipetalous, free; ger- 
mens J-locular ; ovules 2, ascending ; micropyle extrorse inferior 
style subulate ; apex stigmatiferous not thickened. Carpels in fruit 
1-5 (usually solitary, others abortive), free subglobose thick, 2- 
valved. Seed solitary, largely umbilicate ; embryo exalbuminous ; 
cotyledons thick fleshy plano-convex, decurrent below round 
radicle-—Trees ; hairs stellate or lepidote ; leaves alternate entire 
petiolate ; 
entire penniverved, base 3—5-nerved ; flowers in ramified cymiferous 
racemes, terminal or in axils of upper leaves (Zrop. Asia). See

stipules small, little conspicuous or caducous; limb 
2. Christiana DC.'—Flowers nearly of Brownlowia ; stamens all 
fertile. Carpels 5 (or fewer) free at maturity, 2-valved. Seeds so- 
litary pisiform ; testa crustaceous; cotyledons of coloured embryo 
foliaceous ; albumen fleshy.—A tree ; leaves and inflorescence nearly 
of Brownlowia (Trop. West Africa’). 

5-merous, 3-lobed. It is doubtful whether the 
4-lobes, as frequently in Brownlowia, are more

vii. 61. 
The genus is discussed by R. Br., Congo, 
428; Mise. Works (ed. Brnn.), i. 108; the 
calyx is said to be little known, with gynæceum 
or less united for some distance in pairs.
